BADHAMIA 67 



pressed above, plane or slightly umbilicate below ; the peridium 

 simple, more or less translucent from the varying number of 

 innate granules, sometimes covered with circular flat masses 

 of lime, gray except the point of attachment to the stipe which 

 is brown ; stipe short, black, rough, plicate ; capillitium dense 

 at the centre, radiant at the periphery where it meets the spo- 

 rangial wall, white ; spores violaceous black, minutely warted, 

 12-15 p. 



This is a beautiful species, easily known by its discoidal or 

 almost annulate sporangia mounted upon short dark black 

 stipes. The stipe in western collections is sometimes very 

 short, but always suffices to raise the sporangium, a little at 

 least, above the substratum. Sessile and plasmodiocarpous 

 forms do occur with the typical stipitate phase, but may be 

 regarded here as elsewhere as indicative of incomplete devel- 

 opment. Plasmodium cream colored, or pale yellow.

Sporangia clustered, spherical or ovoid, large, sessile or 

 mounted on long thin strand-like stalks, blue gray, violet irides- 

 cent or cinereous, smooth or more often rugulose ; the stipes 

 when present poorly differentiated, as if thread-like filaments 

 and strips of the plasmodium, often branched and always 

 reclining or even prostrate ; hypothallus none ; capillitium a 

 large-meshed open network of rather slender tubules, the 

 nodes unequally developed, white with the enclosed lime; 

 spores not strictly adherent though not without some ten- 

 dency to stick together, delicately warted, bright violet brown,
